Wanna be a rock star? Join the U.S. Air Force! It seems to be working for Staff Sargeant Angie Johnson. She and a few fellow members of the 571st Air Force Band formed a band called Sidewinder, and have been entertaining troops in the Middle East. A video of Sidewinder performing Adele's blues hit "Rolling in the Deep" has gone viral on YouTube, prompting "The Voice" host Carson Daly to invite Angie to audition for the hit TV show.  Check out the video, then tell me....would you want to compete with her...or just wait for next season?
